The net transport of surface water set in motion by wind. Due to the Ekman spiral phenomenon, it is theoretically in a net direction of 90 degrees to the right in the Northern Hemisphere. 90, right Ekman transport is theoretically _____ to the _____ in the Northern Hemisphere
2xSMX or STC+2xMRC. Spatial multiplexing (often abbreviated SM or SMX) is a transmission technique in MIMO wireless communication to transmit independent and separately encoded data signals, so-called streams, from each of the multiple transmit antennas. Therefore, the space dimension is reused, or multiplexed, more than one time.
WDM systems are divided in different wavelength patterns: conventional or coarse and dense WDM. 1  Conventional WDM systems provide up to 16 channels in the 3rd transmission window (C-band, around 1550 nm) of silica fibers.  Dense WDM (DWDM) uses the same 3rd transmission window (C-band) but with denser channel spacing. Channel plans vary, but a typical system would use 40 channels at 100 GHz spacing or 80 channels with 50 GHz spacing. Some technologies are capable of 25 GHz spacing (sometimes called ultra dense WDM).
